CYLINDER-SCRAPER.

Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed April 15, 1916. Serial No. 91,384.

To all whom z5 may concern:

Be it known that I, RANDALL L. MEADER, a citizen of the United States, residing at Portland, in the county of Cumberland and tate of Maine, have invented certain new and useful Improvements in Cylinder- Scrapers, of which the following is a speciication.

The present invention relates to cleaning devices, and more particularly to new and useful improvements in cylinder sera-pers.

The primary object of my invention is to provide a cylinder scraper which is simple in construction, strong and durable, and effective in operation, the scraper being formed in a plurality of sections and having a pivotally connected handle forv manipulating the same, some portions of the scraper being formed to facilitate reaching remote spots in a cylinder. The invention is particularly adapted to use in removing carbon and other deposits from the interior of .internal combustion engine cylinders. Of course, I do not limit the use of my invention to this since the scope of its application is practically unlimited as a scraping implement. y

Other objects and advantages to be derived from the use of my improved cylinder scraper will appear from the following detail description and the claims, taken with an inspection of the accompanying drawings, in which- Figure 1 is a perspective view of a cylinder scraper embodying the improvements of my invention, and

Fig. 2 is a transverse sectional view of the same taken at the handle connection.

- Referring more particularly to the draw-k ings, wherein similar characters of reference 1 designate like and corresponding parts throughout the various views, 1 designates in its entirety my improved cylinder scraper, which embodies a plurality of oppositely arranged various sized channel members 2, 3, 4 and 5. I do not limit myself yto the provision of only four of the channel members as shown, since any number of the channel members might be provided.

As best shown in Fig. 2, the channel members 4 and 5 are embraced by the channel members 2 and 3 and are arranged longitudinally thereof, all of the channel members being permanently attached by means of rivets 6 or the like. The outer marginal edges of the channel members designated 7 are formed to provide cutting edges for removing' carbon depositsand the like from dat or curved surfaces.

One end of the cleaning element 1 is inclined by means of diagonally forming the end edges of the channel members as indicated at 8 in Fig. 1. The edges 8 are formed to provide cutting edges for reaching remote spots on an internal combustion engine cylinder. The outermost channel members 3 and 5 are recessed as at 9 adjacent their end' portions to form right angular cutting sections, which will be found useful in removing deposits from fianges, piston rings, and the like. The upper channel members 2 and 4 are provided with curved end portions 9 which also form cutting edges for facilitating access to remote points.

I provide a manipulating handle 10 formed of a bar ofiron having one end thereof squared as at 11 and journaled on a` rod 12 extending through the channels 2 and 4 of the shorter side of the scraping member. The ends of the rod 12 may be rivetedl or otherwise secured in the correct position. The outer free end of the handle 10 is provided with a loop 13 forming a linger engaging portion to be grasped by the user.

When using my improved scraper the edges 7 may be employed for removing carbon deposits and the like from the peripheral surface of the cylinder, and the ed es 8 may be employed for removing carbon rom the cylinder head. The functions of the cutting edges 9 have been set forth hereinbefore and it will be seen that in the provision of my improved scraper I Yhave produced a Vdevice which is cheap in construction, strong and durable, and effective in operati-on, it being possible to easily renew the parts in the event of breakage, or to sharpen the cutting-V edges when necessary. From the above descriptiontaken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, operation and advantages of my invention may be had, and while I have shown and described my invention as embodying a specific structure, I desire that it be understood that I may make such changes on said structure as do not departfrom the spirit and scope of the invention as described.

What l claim as new and desire to secure by Letters Patent is:

l. ln a cleaning implement, a scraping member comprising a plurality of reversely arranged .U-shaped members having alined cutting edges, the smaller channels being longitudinally arranged within the larger channels, one end edge of said channel members being inclined providing a cutting edge, a handle pivotally connected to the shorter side of the scraping member by means of a rod extending through the U-shaped channels, and the said handle being adapted to be seated in the smaller channel to facilitate the insertion of the cleaning implement.

2. ln a cleaning implement, a scraping member comprising a plurality of reversely arranged 'll-shaped members having alined cutting edges, the smaller channels being longitudinally arranged within the larger channels, the end edges of one end of the larger channel members being inclined, having the end edges of one larger channel supplemental to the adjacent and oppositely y arranged larger channel member, and a handle pivotally connected to the said cleaning implement for the purpose described.

3. In a cleaning implement, a cutting ele- Copies of this patent may be obtained for ment formed of a plurality of various sized reversely arranged channels having cutting edges, the smaller channels being longitudinally arranged within the larger channels, and a handle pivotally engaged therewith.

a. ln a cleaning implement, a scraping element comprising a plurality of reversely arranged nested channels having alined cutting edges, the end portions thereof being beveled for cutting edges, and the opposite end portions thereof being recessed to form angular cutting edges.

5. ln a cleaning implement, a scraping member, comprising a plurality of reversely arranged U-shaped members having alined cutting edges, the smaller channels being longitudinally arranged within the larger channels, the'end edges of one end of the channel members being inclined having the end edge ot the channel member of one side supplemental to the adjacent and oppositely arranged channel member providing a cutting edge, and the other end or" the longer side being recessed to form a right-angular cutting section for the purpose described.

ln testimony whereof l aiiiX my signature hereto.

RANDALL L. MEADER.
